Investing in water is not a bad idea too. I mean consumer defensive stocks in general is not a bad investment. Food, drinks, toothpaste, toilet paper, housing materials, tobacco, oil, pharmacy, minerals… These are all good businesses that print money. Most of them pay dividends too. So you can create a nice passive income which is enough to pay for your monthly expenses when you own enough shares in these businesses.
It certainly beats owning FIAT in a bank account that’s for sure. Only financially illiterate people do that.
